Abstract In this work, the total chromium analysis of the liquid and solid waste s released from Sheba tannery industry was conducted to assess the extent of pollution of the environment. Accordingly, sampling sites termed general line, saline line, chrome line, primary and secondary treated wastewater for wastewater samples, and general solid wastes shaved skins; chrome split and shaved hides, primary and secondary sludge for solid waste were investigated under this study. Total chromium in liquid and solid wastes sample were determined by FAAS and UV-Visible Spectrophotometry. The levels of total chromium concentration in the wastewater using FAAS were: 280.462 ± 9.604, 152.608 ± 6.287, 710.828 ± 12.659, 18.475 ± 0.158 and 8.022 ± 0.363 for general line, saline line, chrome line, primary and secondary treated wastewater respectively. The concentrations of total chromium in solid wastes were: 251.533 ± 4.802, 224.135 ± 1.815, 437.997 ± 13.088, 234.409 ± 4.801 and 19.388 ± 0.669 for general solid waste, shaved skins; chrome splitting and shaved from hides, primary and secondary sludge, respectively . The mean concentrations of Cr in liquid and solid wastes were higher than the recommended maximum limit by USEPA and WHO. The paralleled liquid and solid wastes were compared using bar graph and unpaired t -test and resulting significant difference between the samples. Comparison of the precision of the two methods using bar graph and f-test, and a remedial action also involved in the discussion. Generally, the two methods were equally precise at 95% confidence interval for determination of total chromium in liquid and solid wastes.
